Levers For an example a second class lever is a wheel barrel. You use your hands as the effort force. The load is anything you want to move or carry. The fulcrum is the wheel or wheels.
Inclined Planes Inclined planes are ramps.Inclined planes help you lift heavy objects. Inclined planes are used in home movers companys.
Wedge A wedge is two inclined planes together. A ax is an example of a wedge.
Scissors A scissor is a compound machine. A scissor are two wegdes, that are arranged as two first class levers.
Pulley A pulley makes things easier to lift almost like a inclined plane. There are three types of pulleys. Fixed,moveable,and fixed moveable pulleys.
+ Do Now Why do we use ramps to move heavy objects to higher places?
PHYSICAL SCIENCE SIMPLE MACHINES Abney Elementary.
Lesson 3: How are work and Motion related?. Work – the result of a force MOVING an object.
Levers can make it easier for people to lift heavy objects or open things. The object being moved by a simple machine such as a lever is called a load.
SIMPLE MACHINES Sikes & West S4P3a: Identify simple machines and their uses.
Mechanical Advantage The measurement of how useful a machine is to the job.
Simple Machines. Tools that make work easier lever.
Levers A lever consists of two parts-a bar or plank and a fixed point, called a fulcrum.

Chapter 6 Simple Machines. How Do Simple Machines Help People Do Work? Vocabulary: Lesson 1.
Work, scientifically speaking, is done on an object when a force is applied to move it a certain distance. IMPORTANT! The distance (displacement) in this.
Gears and Pulleys! Allison. What Is A Gear? A gear is a toothed wheel. The gears' teeth connect with another gears and turns.
My study of simple machines. A gear is a device that transfers motion from one part of a machine to another Gears.
THEY MAKE LIFE EASIER BY : JOE BEUKERS One type of lever is a wheelbarrow. Levers can make it easier for people to lift heavy objects or open things.
Simple Machines A simple machine is a device that can multiply a force or change the direction of a force.

What is mechanical advantage? The force you apply to a machine is called the effort force (input force) The force that the machine applies is the resistance.
Chapter 11 work and machines. Anytime that you exert a force and cause an object to move in the direction of the applied force you do _________. work.
Machines, Machines, Machines. When a force moves an object in the direction you are pushing or pulling that object Work.
A push or a pull Force. A force being applied on an object that causes the object to move a distance ? = f x D Work.
Pay attention. Simple Machines Simple machines assist us in doing work by creating a mechanical advantage. They do not change the amount of work; they.
A SIMPLE MACHINE HELPS US DO WORK EASIER. A SIMPLE MACHINE HAS FEW OR NO MOVING PARTS. There are 6 types of simple machines.
They are made with FEW or no moving parts. WHEEL & AXLE SCREW WEDGE INCLINED PLANE PULLEY LEVERGEAR.
Simple Machines SOL 3.2. Simple machines are tools used to make work easier.
SIMPLE MACHINES NOTES. Simple Machines A simple machine is a device that helps reduce the amount of force required to do work. Work is done when a force.
Simple Machines There are six kinds of simple machines: 1. Inclined Plane – 2. Pulley- 3. Lever – 4. Wheel and Axle- 5. Screw – 6. Wedge - ramp top of.
Levers. First Class Lever Fulcrum is between input force and the load Always change the direction of the input force.

Simple Machines Grades 3-4 Created by: Audrey Janco.
MACHINES Devices that make work easier by changing the size and/or the direction of the force. They will not do work for you.
Machine- a device that makes work easier by changing the direction or size of the force.

Pulleys Simple Machines. Pulleys are used to help lift heavy objects.
Machines and Mechanical Advantage Archimedes (Greek mathematician, 287 to 212 B.C.) said, “Give me a place to stand and I will move the Earth,” meaning.
Simple and Complex Machines Simple Machines- the ability to do work Complex Machines- two or more simple machines that work together to do work.
Pulley. What is a pulley? Answer: A pulley is a simple machine that consists of a wheel with a groove in it and a cord that fits into the groove. A load.
Simple Machines Simple machines are basic machines that are the basis for all other forms of machines. There are six types of simple machines: 1.
